Abstract	It is well known there are lots of factors influence cutter efficiency and tool life for boring operations. The key problem is how much each influenced and where is the best balance point. This paper uses the orthogonal test method to simulate and verified the influence by the most two important rock parameters, like rock confining pressure and rock's uniaxial compressive strength. Firstly, we used the CSM model and designed a new test mechanism. In the simulation part, we use Rock Failure Process Analysis in simulates the rock fragments and the changes of stress field. With these new numerical algorithms, we can simulate the mass and cutting forces in the boring, and we finally find each balance point in the real boring in different cutting parameters. And we also updated a new liner cutting test experimental mechanism, which can simulate the real boring operations in the lab when we set different cutting parameters. We use the simulation and test method to verify our predicting result. We show that we simulate three kind of lateral pressure in our test and simulation for 17 inches cutter ring in our cutting test, and we also simulate and test three kinds of rock in our test and find different affection on the cutting. However, since we understand the complex of different factors we can bound the balance point to those values in certain boring condition.
